A preparative high-speed counter-current chromatography method for separation and purification of liensinine, isoliensinine and neferine from seed embryo of Nelumbo nucifera GAERTN was successfully established by using n-hexane-ethyl acetate-methanol-water (5:8:4:5, v/v, containing 0.5% NH(4)OH) as
The effects of isoliensinine (IL), a bisbenzylisoquinoline alkaloid extracted from the Chinese traditional medicine seed embryo of Nelumbo nucifera Gaertn., on bleomycin (BLM)-induced pulmonary fibrosis in mice were investigated. Seventy-two male Kungming mice were divided randomly into eight groups
This study was designed to explore the effects and mechanism of isoliensinine (isolie) from embryos of Nelumbo nucifera on type 2 diabetes and dyslipidemia in vivo and in vitro. The in vitro study showed that isolie increased the GLUT4 translocation by 2.5-fold in L6 cells. Furthermore, after 4
An application of mass spectrometric methods has been developed to characterize, prepare and quantitatively analyze three bisbenzylisoquinoline alkaloids (liensinine, isoliensinine and neferine) from embryo of the seed of Nelumbo nucifera Gaertn. Initially, an analytical method based on liquid
A rapid and specific HPLC method has been developed and validated for the simultaneous determination of liensinine (CAS 2586-96-1), isoliensinine (CAS 6817-41-0) and neferine (CAS 2292-16-2) in rat plasma. The sample was prepared by a liquid-liquid extraction with diethyl ether and the recovery was
The inhibitory effects of isoliensinine (IL), a bisbenzylisoquinoline alkaloid extracted from the seed embryo of the traditional chinese medicinal herb Nelumbo nucifera Gaertn, on the proliferation of porcine coronary arterial smooth muscle cells (CASMCs) induced by angiotensin II(Ang II) and its
Isoliensinine (isolie) is an alkaloid produced by the edible plant Nelumbo nucifera. Here, we unveiled that isolie was able to provoke HepG2, Huh-7, and H22 hepatocellular carcinoma (HCC) cell apoptosis. Isolie decreased NF-κB activity and constitutive phosphorylation of NF-κB p65 subunit at Ser536
Isoliensinine, liensinine and neferine are major bisbenzylisoquinoline alkaloids in the seed embryo of lotus (Nelumbo nucifera), and exhibit potential anti-cancer activity. Here, we explored the effects of these alkaloids on triple-negative breast cancer cells and found that among the three
Six alkaloids were isolated from the green seed embryo of Nelumbo nucifera growing in Ruichang, Jiangxi province. On the basis of physiochemical properties and spectroscopic methods (UV, IR, NMR, MS) they were identified as: lotusine, nuciferine, pronuciferine, liensinine, isoliensinine and
OBJECTIVE
We attempted to ascertain if bisbenzylisoquinoline alkaloids, liensinine and isoliensinine from Nelumbo nucifera Gaertner have antidepressant-like effects and compare the effects with those previously obtained by their analogue neferine.
METHODS
Using mice, the forced swimming test (FST)
Preparative separation of alkaloids from embryo of the seed of Nelumbo nucifera Gaertn has been successfully performed for the first time using pH-zone-refining counter-current chromatography. Two kinds of two-phase solvent systems were applied to preparative CCC isolation. The first was the system
A new high-speed counter-current chromatography method for semi-preparative separation and purification of alkaloids from embryo of the seed of Nelumbo nucifera Gaertn was developed by using pH-gradient elution mode. Diethyl ether was used as the stationary phase of the two-phase solvent system and
Preparative counter-current chromatography (CCC) isolation of liensinine and its analogues, isoliensinine and neferine from embryo of the seed of Nelumbo nucifera GAERTN. has been successfully performed for the first time using upright coil planet centrifuge with four multilayer coils connected in
Counter-current chromatography (CCC) is an efficient liquid-liquid partition chromatography technique without support matrix. Despite there are many significant advancements in the CCC separation of natural products especially for non-ionic neutral compounds, CCC isolation of ionic compounds
